What is Litmus?

Litmus is a comprehensive, AI-powered testing and evaluation platform designed to empower developers building and deploying LLM-powered applications. It provides the tools and insights needed to ensure the reliability, performance, and safety of generative AI solutions.

The Challenges of LLM Testing

Testing LLM-powered applications presents unique challenges compared to traditional software testing:

• Non-deterministic Outputs: LLMs can produce varied outputs for identical inputs, making traditional testing methods unreliable.
• Difficulty in Defining "Correctness": Evaluating LLM outputs often involves subjective judgments and nuanced assessments of quality, relevance, and context.
• Potential for Biases, Hallucinations, and Safety Issues: LLMs can inherit biases from training data, generate factually incorrect information, or produce harmful content, requiring careful scrutiny and mitigation strategies.

Litmus: A Comprehensive Solution

Litmus addresses these challenges with a suite of features designed to streamline the testing and evaluation process:

1. Flexible Test Templates:

• Create reusable test templates with various parameters and inputs to cover diverse scenarios.
• Define evaluation criteria and metrics tailored to your specific application requirements.

2. Automated Test Execution:

• Submit test runs using templates and provide test data, automating the execution process.
• Monitor progress and receive notifications upon completion.

3. Detailed Result Analysis:

• Visualize detailed results with clear pass/fail indicators and LLM assessments.
• Gain insights into model performance, identify areas for improvement, and track progress over time.

4. Proxy Service for Enhanced Monitoring:

• Capture and analyze LLM interactions through a proxy service.
• Explore proxy logs to understand LLM usage patterns, debug issues, and optimize performance.

5. AI-Powered Evaluation:

• Leverage AI-powered tools to assess the quality, relevance, and safety of LLM outputs.
• Detect biases, identify hallucinations, and ensure the responsible use of your AI models.
